Niu Xiaoqiang nodded very cooperatively: "I know, I will never shake you out of Sister Huang." ”

He stretched out his hand as he spoke: "You give me the key, and if anyone finds out, I will say that I stole it from my desk." ”

Huang Li looked left and right and found that there was no one around, so he handed Niu Xiaoqiang the key to the door of the research room, and whispered: "Remember to return it to me as soon as you run out." ”

"Don't worry, as long as I'm done, I'll definitely return the key to you as soon as possible. ”

After the two reached an agreement, they went to the factory cafeteria to eat like no one. Niu Xiaoqiang ate super fast, Huang Li hadn't finished half a bowl, he was already wiping his mouth, "Sister Huang, you eat slowly, I'll go to the research room to study." ”

Throughout the afternoon, Niu Xiaoqiang was studying the experimental literature of Sanyang Tractor Factory, and had a very deep understanding of how to do experiments.

At five o'clock in the afternoon, the first batch of trial diesel engine parts has been made, the workers originally wanted to work overtime to finish the parts, the factory director Han Shuren saw that Fang Dongping's energy was a little weak, so he rejected the workers' request to work overtime, he said to the workers: " Workers, I know that everyone wants to complete the trial production work as soon as possible, so that the new generation of products can be put into production as soon as possible, but this matter is not urgent, in order to ensure that our quality can meet the requirements, we should listen to and accept the guidance and opinions of Fang Gong, Fang Gong has been busy all day today, has been very tired, let's rest for a night, tomorrow to talk about it. ”

Han Shuren's words were very reasonable, and the workers dispelled the idea of working overtime when they heard this.

After getting off work, Niu Xiaoqiang followed Fang Dongping to the cubicle of the factory canteen, Han Shuren was not ambiguous at all, and prepared a table of good wine and good dishes for Fang Dongping, there were two large pots of roast chicken and duck, and the wine was Wuliangye.

Seeing this, Fang Dongping reminded with a serious expression: "Xiao Han, forget it today, next time you won't be allowed to be so extravagant and wasteful, I understand your intentions, there is no need for us to engage in these fictitious things." ”

Han Shuren hurriedly smiled and said: "Elder Fang, I know that you are a very frugal person, but you have helped our factory so much, we should treat it well, besides, this table of banquets is bought in addition to wine, and the chickens and ducks on the table are all raised by me, but it doesn't cost a penny in the factory." ”

Fang Dongping's face softened when he heard this, he smiled and nodded: "I won't talk about the dishes, next time you don't buy Wuliangye, just play some loose wine to entertain me, although I like to drink, but I don't pay much attention to this aspect." ”

In the first few years, Wuliangye cost three yuan and seven cents a bottle, and Moutai cost eight yuan a bottle, and it needs to be purchased with a ticket, which is very expensive for ordinary people, but it is nothing for the factory. Section Chief Wang originally wanted to persuade him, but was stopped by Han Shuren.

Han Shuren knows Fang Dongping's character very well, since he has already said so, there is nothing polite to talk about, saying too much will only make him disgusted.

I saw Han Shuren smile and said, "Okay, I'll listen to Elder Fang, and I'll let the logistics department go and get some loose wine tomorrow and come back." ”

Fang Dongping laughed, raised his glass and said, "That's right, come on, come on, in order to wish tomorrow's test success, let's have a toast first!"

Driven by Fang Dongping, the atmosphere on the wine table was very harmonious, and everyone else drank happily, only Niu Xiaoqiang always scratched his ears and cheeks, looking a little absent-minded.

Niu Xiaoqiang was waiting for this wine to disperse, so he could go to the research room to do research. But these people drank endlessly, and every time they took a sip, they had to stop and talk for a long time before they took a sip, which made Niu Xiaoqiang almost die in a hurry.

I finally waited until the table was over, and it was already nine o'clock in the evening. Niu Xiaoqiang helped Fang Dongping into the factory guest house to lie down and sneaked out.

The guest house of Sanyang Tractor Factory is next door to the factory, Niu Xiaoqiang in order to avoid being discovered, directly climbed over the courtyard wall into the factory, and then bent his waist and drilled into the factory like a thief. It wasn't until he entered the research room that he breathed a sigh of relief.

After resting for a while, Niu Xiaoqiang opened the black metal on his back, he put the black metal under the microscope, adjusted the magnification, and observed it carefully.

When this black metal is magnified a thousand times, you can see a very regular texture, which is somewhat similar to carbon steel, but the structure is more compact than carbon steel.

Niu Xiaoqiang used experimental equipment to conduct a detailed study of this piece of ferrous metal, and through more than two hours of research, he found that this piece of ferrous metal is very fire-resistant, and the hardness is extremely high, at least ten times harder than the metal used to make tractor engines, and the compression resistance and ductility are also extremely strong.

Although Niu Xiaoqiang had never been in contact with materials science before, he could also feel the great utilization value of this ferrous metal. It is no exaggeration to say that if this metal is used to make high-power diesel engines, then the level of domestic diesel engines will immediately be improved by several grades!

Diesel engines use cast iron blocks, while gasoline engines use cast aluminum blocks, which is mainly due to the difference in the service objects of the two engines.

Gasoline engines are generally installed in cars and are generally household products, so the requirements for engine power are not very high. The cast aluminum cylinder block has the characteristics of light weight, which helps to reduce fuel consumption and is very in line with the economy of household products, so the cast aluminum cylinder block is generally used in automobile engines.

Diesel engines are different, diesel engines are generally used in heavy machinery, such as bulldozers, heavy trucks, agricultural vehicles, ships, etc., these equipment need strong power to meet production needs, cast iron cylinder block has a stronger thermal load capacity, greater potential in the power surface, and corrosion resistance and strength are also higher than cast aluminum cylinder block, so it is widely used in the industrial field.

Niu Xiaoqiang stared at the test results for a long time, and suddenly said this: "The weight of this material seems to be only a little heavier than aluminum, but its performance in all aspects is stronger than that of aluminum materials.

After he finished speaking, his eyes almost glowed with gold, as if a road paved with money had been opened for him, waiting for him to pick up the money.

Stimulated by the economy, Niu Xiaoqiang urgently needed to figure out the production process of this ferrous metal. It's late, and he doesn't know how to make steel, so it's worth giving up on the idea for now.
